Do you seriously want to automate silicon?

(Or do you genuinely enjoy fixing DRC violations manually at 3:00 AM while questioning your life choices?)

BUILDSTACK EDA LAB - v2.0

Synthesize SiliconWith Intent._

Buildstack is a semiconductor automation lab building agentic tools for the next generation of chip design. No manual EDA. No boilerplate constraints. No failed DRC loops. Just intent to silicon.

What We're Building

Each tool in the Buildstack ecosystem solves one hard problem in chip design automation.

LIVE · v1.0

AgentIC

Autonomous Hardware Synthesizer · v3.0

Synthesize synthesizable silicon. Natural language in, GDSII out. Describe a custom CPU, peripheral, or logic gate array in plain language. AgentIC handles formal bounds checking, self-healing timing verification, and physical standard cell placement.

Repair Loop

It Fixes Itself.

Most EDA pipelines stop at the first violation. AgentIC treats every error as an input.

Run StageDetect ErrorDiagnose Root CauseApply Fix + Retry747 DRC ErrorsResolved to ZeroUntil clean loop

Compiler-Guided Feedback

AgentIC parses raw Yosys and OpenLane logs, extracts specific violations, and surgically patches only the failing lines instead of rewriting the full design.

Closed-Loop Physical Repair

Timing slack violations and congestion maps are fed back into RTL. AgentIC can insert pipeline stages or adjust floorplan density without touching the rest of the design.

Zero Human Checkpoints

The loop runs until DRC, LVS, and formal sign-off are clean. Every repair is logged with a diff of what changed and why for a full audit trail.

Autonomous Pull Requests

Zero-Touch DRC Resolutions.

AgentIC doesn't just flag errors; it surgically patches your RTL and Netlists. Review diffs, approve branches, and push to production with confidence.

Methodology

From Intent to Silicon

The Buildstack methodology distilled into four precise stages.

Step 1

Define Intent

Natural language or structured spec input.

Linear progression

Step 2

RTL Generation

AgentIC synthesizes verified Verilog.

Linear progression

Step 3

Physical Design + Repair Loop

OpenLane runs P&R. On any DRC or LVS violation, the Repair Agent intercepts, diagnoses, patches, and retries until the layout is clean.

Loop-aware stage

Step 4

Tape-Out Ready

DRC and LVS clean GDSII export.

Linear progression
